14.3.3.1 Boot-Mode and Clock Selection
Note:
Clock selection is not available with the i.MX27 module.
The i.MX27 controller is able to boot from different devices as described in
chapter 6.1.2 . To have a
choice from which device the controller should boot the boot signals BOOT0 to BOOT2 are connected
to the dip-switch S5 on the i.MX Carrier Board.
With S5 on the i.MX Carrier Board it is possible to select the status of BOOT0, BOOT1 and BOOT2.
For detailed information see
Table 23 , Table 24 and Table 25 below.
Note:
A standard Boot Configuration is already set on the i.MX27 module. Here you can change the Boot
Mode to an alternatively mode. For standard Boot Configuration all dip switches have to be in OFF
position.
